Dissimilar Pipe: Deflection Test

Our Dissimilar Pipe Coupler was put to the test. As you can see it withheld a 3,300 lb. concrete pipe while not allowing deflection (when two pipes don’t line up properly and are lined up at a degree of an angle.) Our coupler seals the joint between the two pipes so there is not infiltration/exfiltration.
